SPEED

If you have spent much time driving, you probably have a good sense of speeds between about 10 and 70 miles per hour. But what are these in meters per second?

What do we mean when we say that something is moving at 10 m/s?

To get a better sense of what these values really mean, do some observations and calculations on your own:

calculate typical car speeds in meters per second.

estimate jogging and walking speed by timing yourself; convert the measurements into both m/s and mi/h.

determine the speed of an ant, snail, or falling leaf.
